I've never had a problem with racket length before and after stringing. I almost always have at least two or more of the same rackets and after I string one, I measure it to the unstrung one. They are always the same length.

Way back in the day when I started stringing, I had heard constant pull strung tighter than crank (the reason why made sense). At that time, I calibrated my crank to be about 1.5lbs. higher than it actually was to more closely simulate constant pull (CP). Master PeteLSD told me his experience was, CP vs. Crank was a difference of about 3lbs. After experiencing both, I concur.

So far I've strung: 2 x new Ti10s, 2 x Cab20s, 2 x Chao Pai NP728s with the Wise and there have been no problems at all. The highest I've strung on the Wise so far is 27.0 x 29.7lbs. (~28.3lbs.) which feels like my crank at about 28.25 x 31.0. (~29.6lbs.). Take into account the 1.5lbs. I added to the crank, that's about 2.8lbs., almost a 3lbs. difference.

Master Pete is always right when it comes to stringing...

If there is a difference then something is wrong.

glad to see less people having complications with it... (after some terrifying posts on tennis-stringer-fora) good news!

some more questions.. How does the string-clamp work, did you need to adjust it?
I also read you cp728 sell-post...
are you stringer two-piece, top-bottom now? Is it because of the wise?
(curious lad, aren't I? )

Yes, I'm very pleased with the Wise. It's an extremely consistent machine. There are only three minor gripes I have:

1) The gripper at even the tightest setting is not sufficient for badminton string. I added a piece of leather grip and it's just fine now.

2) The control panel is a quality plastic but it's secured by industrial two sided tape. On both edges, the panel kind of lifts up and I have to push down every now and then. The plastic panel won't come off but it's just funny when it sticks up...doesn't exactly instill confidence.

3) I wish the gripper was closer to the edge of the machine, that way I could still get away with my normal pre-string method. Now I'm in the same boat as most of you stringers needing extra length on the two middle loops to start pulling. It's a minor pain but well worth the performance return I get from electronic constant pull (ECP).

I now only string 2PTD (2-Piece Top Down). I find the string job is more uniform, more crisp and the upper half of the string bed is just more responsive.

Also, the 2nd most important factor (next to more crisp/responsive) for me is going top down, I don't put as much stress on the final tie-off. I'd rather do 34lbs. on the bottom tie-off than the top one (add 2-3lbs. to offset the tension loss).

For pro stringers and players that are very sensitive to string tension differences, ECP is significantly better than crank. I highly recommend ECP if you need it or your performance goals demand it.

I still pre-string. But I need the extra length for the two loops so what I do is do a normal pre-string, then pull out the last main and move all that string back to center and now I have just enough.

I know some others tie the string around the shaft but I don't want to risk damaging the string.

In the last 3 months I've started going higher and higher in tension. As a result, I play better and better. 3 months ago I was at 26-27lbs. Now I'm at 30-32lbs. The 30-32lbs. is constant pull, not crank. If I keep playing better at higher tensions, I might try Jens Erikson's 35lbs.

tying around the shaft? I don't follow... How/why/when?

I just tried 36lbs once, on a w7, for fun... Never got around to playing a serious match with it..
Frankly, I tend to have some mishits issues (even) at 28lbs...
I'm not too proud to admit it but I guess it's because I'm hitting harder, and have to hit hard under pressure more..

What really brings my piss to a boil is that out of all the mishits I break strings with, 90% are midcourt kills...
